A statistician hired by the state is attacking the methodology of another expert who says hundreds of thousands of Pennsylvania voters lack the photo identification they would need to cast ballots under a pending law.
William Wecker testified Thursday in Commonwealth Court, criticizing the work of statistician Bernard Siskin that's a key part of a lawsuit seeking to overturn the law on constitutional grounds.
Wecker says Siskin overstated the number of voters without IDs by failing to adequately consider voters who have died, moved out of state or are barred from voting because they are incarcerated felons.
Wecker claimed Siskin's report also did not adequately account for voters who have acceptable non-government IDs from sources such as universities or nursing homes.
Thursday is the ninth day of the trial.
